rrr-Ess Eon coMrREssINGVAnD BALING COTTON AND OTHER MATERIALS.

T0 all whom t may concern Be it known that I, ARTHURELPHINSTONE GUrrMrNs, a subject of the King of Great Britain, residing at 12 Belsize avenue, Hampstead, in they county` of Middlesex, England, have invented new and useful Improvements in Presses for Compressing and Baling Cotton and other Materials, of which the following is a specification.

rhis invention has reference to horizontal presses for baling cotton, jute or other and especially to presses in which the bales are formed by pressure in the direction of their length for which a British patent wask ygranted to Claudius J ames Ash, (a communication from Arthur 426:2 of 1883, in which was described a vertical press having a single fixedbaling chamber and a plurality of revolving filling boxes rotating on upright columns, the charges from each box beingpushed, one' by one, into the baling chamber by the action of being retained in the baling chamber by revolving fingerspreviou's to the final compression by the large ram of the telescopic system.

ln the specications of the British Patentv No. 4367 .of 1904: and the United States Patent No. 590681 granted Ito Arthur Elphinstone Cummins are .described-baling presses, now in common use,rhav.ing a single baling chamber in which the bales are finished, combined with one long loose cotton filling box, all in one line. Such pressesare only suitp able for a very large outturn in bales.k

The object of the present invention is to provide a perfect machine at a moderate cost for making bales of any required density pressed in the direction of' their length and having a moderate outturn of bales more in accord with the wants of many pressing establishments, and to construct a.

from the loose lling box is a ram and cylj inder by which the bale is finally compressed, while the preliminary compression of the material is taking place in the preliminary baling chamber.

Between the preliminary and finishing baling chambers isa movable lashing plate extending across the press between the baling chambers. y en itis desired to push the partly condensed material vfrom the preliminary chamber to the finishing chamber the lashing plate is moved away transversely tothe press. When inside the press the lashingv plate the finishing ram on one side, and receives a balancing strain on the other side from the other ram. ln `order to retain a charge in a baling chamber when the ram is withdrawn the sectional area ofthe end of theVA chamber is made slightly larger than ,they

sectional area of the chamber.

Figure 1 is a longitudinal section of the y lefthand end of a press constructed according to this invention, and Fig. 2 is a like view of the righthand end. Fig. 3 is a view simi*- lar to a portion of Fig. 2 but showing the parts in a different position. Fig.l 4f is a transverse section on the line 1Q-1 Fig. 1.

a is the long loose cotton filling box. It is provided with doors (not shown) in the ordinary way.

Z) is a hollow ram in the cylinder c. This ram is guided and supported by a pipe d fixed in thel cylinder and which, during-the second half vof they outwardV stroke of the ram, is in its turn supported by the guide c, which is detachably fixed to andfmoves with the inner end of the ram during the iirst part of the stroke. The guide c fits a portion c1 (of reduced diameter) of the cylinder c and is prevented from passing this by reason of the collar c1' on its rear end. The ram bat this point thereforeseparates from the guide leaving it behind as shown'at Fig. 3. Water ternal diameter of the ram being exposed to pressure, but if and when additional power is required water is also admitted into the cylinder c at c2 the whole area of the ram being then exposed to pressure.

takes the Ventire strain from 1 is admitted throughthe pipe (Z, only the ini f is the preliminary baling chamber and f1 f1 are portions of enlarged diameter near its tWo ends into Which the material eX-y pands and thus retains the compressed charge inthe Lchamber when vthe. ram b is Wlthdrawn.

Theplate L is free to move in tr'ansverseguides 'e' and vis`moved in one direction by the hydraulic rams j andl in the other direction" by the 'Weight y7c'.

Z is ar door acted,y on which, when' the lashing plate 77. is With-y through ivhich it passed, this door acting as a buffer When the plate returns.

m is the finishing ram and m1 plate fixed to it.

The means for returning the Vrams may be of any ordinary type and are not shown.

The operation is as follows :-The box a is is a lashing I filled with loose cotton which is then comvso `so that the three pressed by the ram b into the chamber f, the end of which is closed bythe plate i. The ram b is then Withdravn and the, boX a. lis again filled and its contents compressed into the chamber f. If three chargesrof the'box a are sufficient to form arbale the plate i is now Withdrawn and the third stroke ofthe ram is made longer than the preceding ones charges are forced-together into the finishing chamber g, the end of Whi ch is then again closed by the plate fr. he three charges are then compressed together into a bale by the ram m and the bale is lashed in the ordinary Way and removed from the chamber g. During these operations charges for forming a second bale are being compressed inV the chamber f; these charges are forced into the chamber g as soon as it is empty and so on. l That Iclaim is t t l.
